SHOW BUFFER
Syntax
SHOW BUFFER [SCAN[=address [QUEUEPOINTERS]]]
where:
■ address is the memory address of a section of router code, expressed in
hexadecimal.
Description
This command displays information about the memory buffers in use by router
modules. If no optional parameters are specified, a summary of the buffers in
use is displayed (Figure 1-9 on page 1-96, Table 1-13 on page 1-97).
The SCAN parameter displays more detailed information about buffers usage.
If an address is not specified, the memory addresses of sections of router code
and the number of buffers in used by that section are displayed (Figure 1-10 on
page 1-97). If an address is specified, the addresses of the buffers in use by that
section of router code are displayed (Figure 1-11 on page 1-98). The value for
address is obtained from the output of a previous SHOW BUFFER SCAN
command.
The QUEUEPOINTERS parameter displays additional information about the
contents of the buffers used by the router code section at the specified address
(Figure 1-12 on page 1-98), and is only valid when the SCAN parameter is
specified with a valid address.
The SCAN and QUEUEPOINTERS parameters display low-level debugging
information. Use these parameters only when directed to by technical support personnel.
